Code Audit Labs http://www.vulnhunt.com has discovered a vulnerability
allows remote attackers to execute code on vulnerable
installations of Adobe's Shockwave Player. User interaction is required
in that a user must visit a malicious web site.

The specific flaw exists when the Shockwave player attempts to load a
specially crafted Adobe Director File. When a malicious value is used
during a memory dereference a possible 4-byte memory overwrite may
occur. Exploitation can lead to remote system compromise under the
credentials of the currently logged in user.
